1Git v1.8.2 Release Notes 2======================== 3 4Backward compatibility notes 5---------------------------- 6 7In the upcoming major release (tentatively called 1.8.2), we will 8change the behavior of the "git push" command. 9 10When "git push [$there]" does not say what to push, we have used the 11traditional "matching" semantics so far (all your branches were sent 12to the remote as long as there already are branches of the same name 13over there). We will use the "simple" semantics that pushes the 14current branch to the branch with the same name, only when the current 15branch is set to integrate with that remote branch. There is a user 16preference configuration variable "push.default" to change this. 17 18 19Updates since v1.8.1 20-------------------- 21 22UI, Workflows & Features 23 24 * Initial ports to QNX and z/OS UNIX System Services have started. 25 26 * Output from the tests is coloured using "green is okay, yellow is 27 questionable, red is bad and blue is informative" scheme. 28 29 * In bare repositories, "git shortlog" and other commands now read 30 mailmap files from the tip of the history, to help running these 31 tools in server settings. 32 33 * Color specifiers, e.g. "%C(blue)Hello%C(reset)", used in the 34 "--format=" option of "git log" and friends can be disabled when 35 the output is not sent to a terminal by prefixing them with 36 "auto,", e.g. "%C(auto,blue)Hello%C(auto,reset)". 37 38 * Scripts can ask Git that wildcard patterns in pathspecs they give do 39 not have any significance, i.e. take them as literal strings. 40 41 * The pathspec code learned to grok "foo/**/bar" as a pattern that 42 matches "bar" in 0-or-more levels of subdirectory in "foo". 43 44 * "git blame" (and "git diff") learned the "--no-follow" option. 45 46 * "git cherry-pick" can be used to replay a root commit to an unborn 47 branch. 48 49 * "git fetch --mirror" and fetch that uses other forms of refspec 50 with wildcard used to attempt to update a symbolic ref that match 51 the wildcard on the receiving end, which made little sense (the 52 real ref that is pointed at by the symbolic ref would be updated 53 anyway). Symbolic refs no longer are affected by such a fetch. 54 55 * "git format-patch" now detects more cases in which a whole branch 56 is being exported, and uses the description for the branch, when 57 asked to write a cover letter for the series. 58 59 * "git format-patch" learned "-v $count" option, and prepends a 60 string "v$count-" to the names of its output files, and also 61 automatically sets the subject prefix to "PATCH v$count". This 62 allows patches from rerolled series to be stored under different 63 names and makes it easier to reuse cover letter messsages. 64 65 * "git push" now requires "-f" to update a tag, even if it is a 66 fast-forward, as tags are meant to be fixed points. 67 68 * When "git rebase" fails to generate patches to be applied (e.g. due 69 to oom), it failed to detect the failure and instead behaved as if 70 there were nothing to do. A workaround to use a temporary file has 71 been applied, but we probably would want to revisit this later, as 72 it hurts the common case of not failing at all. 73 74 * "git submodule" started learning a new mode to integrate with the 75 tip of the remote branch (as opposed to integrating with the commit 76 recorded in the superproject's gitlink). 77 78 79Foreign Interface 80 81 * "git fast-export" has been updated for its use in the context of 82 the remote helper interface. 83 84 * A new remote helper to interact with bzr has been added to contrib/. 85 86 87Performance, Internal Implementation, etc. 88 89 * "git fsck" has been taught to be pickier about entries in tree 90 objects that should not be there, e.g. ".", ".git", and "..". 91 92 * Matching paths with common forms of pathspecs that contain wildcard 93 characters has been optimized further. 94 95 * The implementation of "imap-send" has been updated to reuse xml 96 quoting code from http-push codepath. 97 98 * There is a simple-minded checker for the test scripts in t/ 99 directory to catch most common mistakes (it is not enabled by 100 default). 101 102 103Also contains minor documentation updates and code clean-ups. 104 105 106Fixes since v1.8.1 107------------------ 108 109Unless otherwise noted, all the fixes since v1.8.1 in the maintenance 110track are contained in this release (see release notes to them for 111details). 112 113 * An element on GIT_CEILING_DIRECTORIES list that does not name the 114 real path to a directory (i.e. a symbolic link) could have caused 115 the GIT_DIR discovery logic to escape the ceiling. 116 (merge 059b379 mh/ceiling later to maint). 117 118 * When attempting to read the XDG-style $HOME/.config/git/config and 119 finding that $HOME/.config/git is a file, we gave a wrong error 120 message, instead of treating the case as "a custom config file does 121 not exist there" and moving on. 122 (merge 8f2bbe4 jn/warn-on-inaccessible-loosen later to maint). 123 124 * The behaviour visible to the end users was confusing, when they 125 attempt to kill a process spawned in the editor that was in turn 126 launched by Git with SIGINT (or SIGQUIT), as Git would catch that 127 signal and die. We ignore these signals now. 128 (merge 1250857 pf/editor-ignore-sigint later to maint). 129 130 * A child process that was killed by a signal (e.g. SIGINT) was 131 reported in an inconsistent way depending on how the process was 132 spawned by us, with or without a shell in between. 133 (merge 709ca73 jk/unify-exit-code-by-receiving-signal later to maint). 134 135 * After failing to create a temporary file using mkstemp(), failing 136 pathname was not reported correctly on some platforms. 137 (merge f7be59b jc/mkstemp-more-careful-error-reporting later to maint). 138 139 * The attribute mechanism didn't allow limiting attributes to be 140 applied to only a single directory itself with "path/" like the 141 exclude mechanism does. 142 (merge 94bc671 ja/directory-attrs later to maint). 143 144 * "git apply" misbehaved when fixing whitespace breakages by removing 145 excess trailing blank lines. 146 (merge 5de7166 jc/apply-trailing-blank-removal later to maint). 147 148 * A tar archive created by "git archive" recorded a directory in a 149 way that made NetBSD's implementation of "tar" sometimes unhappy. 150 (merge 22f0dcd rs/leave-base-name-in-name-field-of-tar later to maint). 151 152 * "git archive" did not record uncompressed size in the header when 153 streaming a zip archive, which confused some implementations of unzip. 154 (merge 5ea2c84 rs/zip-with-uncompressed-size-in-the-header later to maint). 155 156 * When "git clone --separate-git-dir=$over_there" is interrupted, it 157 failed to remove the real location of the $GIT_DIR it created. 158 This was most visible when interrupting a submodule update. 159 (merge 9be1980 jl/interrupt-clone-remove-separate-git-dir later to maint). 160 161 * The way "git svn" asked for password using SSH_ASKPASS and 162 GIT_ASKPASS was not in line with the rest of the system. 163 (merge e9263e4 ss/svn-prompt later to maint). 164 165 * The --graph code fell into infinite loop when asked to do what the 166 code did not expect. 167 (merge 656197a mk/maint-graph-infinity-loop later to maint). 168 169 * http transport was wrong to ask for the username when the 170 authentication is done by certificate identity. 171 (merge 75e9a40 rb/http-cert-cred-no-username-prompt later to maint). 172 173 * "git pack-refs" that ran in parallel to another process that 174 created new refs had a nasty race. 175 (merge b3f1280 jk/repack-ref-racefix later to maint). 176 177 * After "git add -N" and then writing a tree object out of the 178 index, the cache-tree data structure got corrupted. 179 (merge eec3e7e nd/invalidate-i-t-a-cache-tree later to maint). 180 181 * "git merge --no-edit" computed who were involved in the work done 182 on the side branch, even though that information is to be discarded 183 without getting seen in the editor. 184 (merge 9bcbb1c jc/maint-fmt-merge-msg-no-edit-lose-credit later to maint). 185 186 * "git merge" started calling prepare-commit-msg hook like "git 187 commit" does some time ago, but forgot to pay attention to the exit 188 status of the hook. 189 (merge 3e4141d ap/merge-stop-at-prepare-commit-msg-failure later to maint). 190 191 * When users spell "cc:" in lowercase in the fake "header" in the 192 trailer part, "git send-email" failed to pick up the addresses from 193 there. As e-mail headers field names are case insensitive, this 194 script should follow suit and treat "cc:" and "Cc:" the same way. 195 (merge 6310071 nz/send-email-headers-are-case-insensitive later to maint). 196 197 * Output from "git status --ignored" showed an unexpected interaction 198 with "--untracked". 199 (merge a45fb69 ap/status-ignored-in-ignored-directory later to maint). 200 201 * "gitweb", when sorting by age to show repositories with new 202 activities first, used to sort repositories with absolutely 203 nothing in it early, which was not very useful. 204 (merge 28dae18 md/gitweb-sort-by-age later to maint). 205 206 * "gitweb"'s code to sanitize control characters before passing it to 207 "highlight" filter lost known-to-be-safe control characters by 208 mistake. 209 (merge 0e901d2 os/gitweb-highlight-uncaptured later to maint). 210 211 * When a line to be wrapped has a solid run of non space characters 212 whose length exactly is the wrap width, "git shortlog -w" failed 213 to add a newline after such a line. 214 (merge e0db176 sp/shortlog-missing-lf later to maint). 215 216 * Command line completion leaked an unnecessary error message while 217 looking for possible matches with paths in <tree-ish>. 218 (merge ca87dd6 ds/completion-silence-in-tree-path-probe later to maint). 219 220 * Command line completion for "tcsh" emitted an unwanted space 221 after completing a single directory name. 222 (merge 92f1c04 mk/complete-tcsh later to maint). 223 224 * Some shells do not behave correctly when IFS is unset; work it 225 around by explicitly setting it to the default value. 226 (merge 393050c jc/maint-fbsd-sh-ifs-workaround later to maint). 227 228 * Some scripted programs written in Python did not get updated when 229 PYTHON_PATH changed. 230 (cherry-pick 96a4647fca54031974cd6ad1 later to maint). 231 232 * When autoconf is used, any build on a different commit always ran 233 "config.status --recheck" even when unnecessary. 234 (merge 1226504 jn/less-reconfigure later to maint). 235 236 * We have been carrying a translated and long-unmaintained copy of an 237 old version of the tutorial; removed. 238 (merge 0a85441 ta/remove-stale-translated-tut later to maint). 239 240 * t4014, t9502 and t0200 tests had various portability issues that 241 broke on OpenBSD. 242 (merge 27f6342 jc/maint-test-portability later to maint). 243 244 * t9020 and t3600 tests had various portability issues. 245 (merge 5a02966 jc/test-portability later to maint). 246 247 * t9200 runs "cvs init" on a directory that already exists, but a 248 platform can configure this fail for the current user (e.g. you 249 need to be in the cvsadmin group on NetBSD 6.0). 250 (merge 8666df0 jc/test-cvs-no-init-in-existing-dir later to maint). 251 252 * t9020 and t9810 had a few non-portable shell script construct. 253 (merge 2797914 tb/test-t9020-no-which later to maint). 254 (merge 6f4e505 tb/test-t9810-no-sed-i later to maint).
